for #5,

* rename ebook.rb to be ebook-builder.rb
* add GUI support to (re)order the the sections (aka chapters)
* add GUI support to (re)order the files in display order in a section
* Many things could be better GUI wise - go for it.
* It's TOC that should work well enough to get help_ebook.rb tested
* useless crud in yaml exists - probably
* does not auto parse the nav document and build the TOC automagically
  because that's not a priority. Remember - we still can't render anything
  with acceptable fidelity.

ebook.rb → ebook-builder.rb
